Enables identical protein binding activity. Involved in double-strand break repair; gamete generation; and meiosis I. Acts upstream of or within gamete generation. Located in male germ cell nucleus. Is expressed in several structures, including alimentary system; brain; genitourinary system; integumental system; and sensory organ. Human ortholog(s) of this gene implicated in mosaic variegated aneuploidy syndrome 3. Orthologous to human TRIP13 (thyroid hormone receptor interactor 13).
